Smulders casually revealed the news during an interview with Bustle, where she explained how she connected to the film's themes of motherhood.

"I'm in Sundance and I have a three week old baby, so I can certainly relate," Smulders, 32, told the magazine. "It's my world at the moment, and it's just so prevalent in the world today. I'm very lucky where I have a great career and a huge support system and not every woman has that."
